Abstract: h i g h l i g h t sLaminar burning velocities of ammonia/air flames at high pressures are evaluated. Maximum value of laminar burning velocity of ammonia/air flame is about 7 cm/s. Laminar burning velocity decreases with the increase in the pressure. Markstein length increases with the increase in equivalence ratio. Markstein lengths at high pressure are lower than those at 0.1 MPa. a b s t r a c tAmmonia is expected to be useful not only as a hydrogen-energy carrier but also as a carbon-free fuel.

“…Recently, ammonia has attracted interest as a potential carbon-free energy carrier [5]. Results on oxidation of NH 3 are available from flames [6][7][8][9][10][11][12][13][14][15][16], shock tubes [17][18][19][20][21][22][23][24][25][26][27], and flow reactors [2,[28][29][30]. In addition, a number of modeling studies and reviews of ammonia chemistry have been reported [3,27,28,[31][32][33][34][35].…”

“…High-temperature results at increased pressure are available from recent work in shock tubes and premixed flames. Mathieu and Petersen [27] measured the ignition time for ammonia diluted in Ar at 1.4, 11, and 30 bar, respectively, while Hayakawa et al [15] determined the burning velocity of ammonia/air mixtures at pressures of 1-5 bar. However, studies of ammonia oxidation at low-to-medium temperatures and high pressure are scarce.…”

“…Due to the lack of experimental data in the literature for the previously-mentioned conditions and mixture compositions, an indirect approach is applied in order to validate the computations. In total, 31 experimental datasets from the literature [58,[61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78] are used, as depicted in Table 3, in order to validate the chosen mechanisms (Table 2) at atmospheric conditions, as well as at elevated temperatures (up to 2085 K) and pressures (up to 5.1 MPa). The validation results are shown in Figure 4.…”
